Background:
Although the adverse effects of vascular
comorbidities are increasingly recognized in multiple
sclerosis (MS), the epidemiology of these
conditions remains poorly understood.
Methods:
Using population-based administrative data, we identified
44,452 Canadians with MS and 220,849
age-, sex- and geographically matched controls. We
applied validated definitions to estimate the incidence
of diabetes, hypertension, hyperlipidemia, and ischemic
heart disease (IHD) from 1995 to 2005.
Results:
Of the MS cases, 31,757 (71.4%) were in female
participants, with a mean (SD) age at the index
date of 43.8 (13.7) years.
Over time, the age-standardized
incidence of diabetes rose more in the
MS population (incidence rate ratio [IRR] per year
1.06; 95% confidence interval [CI] 1.03–1.08) than
in the matched population (IRR per year 1.02; 95%
CI 1.01–1.03).
Temporal trends in the age-standardized incidence of hyperlipidemia, hypertension, and IHD were similar in both populations. Among those aged 20–44 years, the
incidence of IHD was higher in the MS population (IRR 1.59; 95% CI 1.19–2.11).
The increased incidence of IHD in the MS population was attenuated among those aged 60 years and older (IRR 1.01; 95% CI 0.97–1.06).
Conclusions:
The incidence rates of diabetes, hypertension, and hyperlipidemia are rising within the MS population. Programs to systematically prevent and treat these conditions are needed.
